Hi @Prowk no way I’ve been after the Asus Strix OC 3090 for months one day. As you may have read turning on reprojection in OpenXR does require a bit of processing power even with a 3090 but well worth it for the extra smoothness.
From what I’ve experienced and read it’s better to set render scaling in OpenXR slightly lower say 70% (I have runtime preview enabled and reprojection ‘always on’ enabled).
In MSFS set TAA with 100% render scaling - if you want to change render scaling further I think it’s better to change it in MSFS instead of OXR because if you have OXR render scaling too high then reprojection is less effective.
Oh yeah if you don’t see the Custom Render Scale option in the Developer Settings, then you’ll need to go back to Microsoft Store select More options (three dots) and look at Downloads and updates and install the latest version 105.2012.21002.0.
